have 5000iu powder and 1ml solvent. im planning 500iu eod dosages

do i just simply mix the two to make 1ml of solution and get 10 slin pins and simply fill them each to the 0.1ml marker (i.e. 1 tenth of the syringe)

i have two kits (in case i ****ed one up). but the solvent amp is weird in that i cant get the solvent to settle at the bottom so if i crack it open it may just spill everywhere - any tips?
